Other USB NotesĪ simple lock/unlock call in vendor mtp commands will allow the host to erase and modify files. Karma uses this to push metadata to the camera and thus muxed into the MP4.

Hardwired sensors can push data to the camera for it to be muxed into the MP4 stream. Also, network scanning can be done via this mechanism. It appears the Karma turns on wifi via GPControl to send fw updates to the camera via buckhorn->coyote. Items such as pairing and turning on wifi/ble can be setup this way. GPControl allows access to WiFi Settings and control via USB. Vendor Specific Commands USB_MTP_EXT_OPCODE_VENDOR_SET Again they have not released their source GPL2! Karma (Kirkwood) talks to Sentinel via the following Vendor commands. AFAIK, the composite device and access to MTP-GCCB only occurs when a Karma is detected by the PD. In addition, this interface can become a composite device and add a CDC USB channel which allows easier access to the GCCB bus. The form factor looks surprisingly similar to the 3.5 Pro Mic adapter and appears to be built to attach to an Arduino.Ī USB host can connect to the GoPro HERO4/5 and not only control, but push metadata to the camera. It appears Rigado is the solutions provider for BLE and HEROBus Devtools. The GCCB on the GoPro HERO5 can run over USB MTP, USB CDC, or i2c depending on what device is detected by the PD / Atmel MCU (Code named Garter device). A simple channel proxy establishes connection and then the session remains open until closed. It's basically a 1 to 1 interface to their APPC commands. This protocol is the same as the GoPro HERO4's and is used for MultiCam syncing as well as complete control and feedback. We've expanded out the HeroBus/GCCB protocol but are not ready to post it yet. USB type-C - Supplement Pins - Muxed dependent on the device found by the PD driver.USB type-C - Power Delivery Protocol - Determines HEROBUS device type.WiFi - Documented pretty well via external resources.USB CDC Serial - Allows for GCCB communications over serial for Karma.Expanded with Karma for GCCB (HEROBUS Protocol) via MTP/USB. USB MTP - Camera to Host connectivity.Bluetooth Low Energy (BLE) - Complete control, feedback and metadata sink.Feel free to send us resources and notes to update this post. We purposely never became members of the Developer Program so that we can share this interface since we feel it should be open for all to use.

We love learning how to "talk" to the GoPro Camera from the various interfaces. This is a continuously updated blog post that contains the various methods which external devices talk to the GoPro Camera.
